ANTIFRICTION"BEARING- SPECIFICATION formingpart of Letters Patent No. 753,619, dated March 1, 1904.

Application filed June 10, 1903- To all whom it may concern:

Be it known that I, WALTER W. OCoNNoR, a subject of the King of Great Britain, residing at East Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and'useful Improvements in Antifriction-Bearings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in antifriction-bearings, and more particularly to that class employed upon vehicles and the like.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and Wherein like numerals of reference-indicate like parts throughout the several views, in which Figure 1 is a longitudinal sectional View of the hub of a wheel, showing my improved bearings in position. Fig. 2 is a cross-section taken through the central part of the casing containing the bearings, and Fig. 3 is a side elevation of one of the annular plates carried upon the shank portion of the axle.

In the accompanying drawings I have shown my antifriction-bearing secured in the hub of a wheel, and in carrying out my invention I provide a tubular casing 1, having the en larged tubular ends 2. Centrally of the tubular casing 1 I provide a partition 3, having. an aperture 4: formed therein, through whichpasses the shank 5 of the axle 6. This axle, near the shank portion thereof, carries the annular vflange 7, having a race 8 formed in its face, in which are partially mounted the balls 9. In the enlarged tubular end 10 of the casing 1' is mounted the annular plate 11, said plate being formed with a race 12, which engages the balls 9, also partially carried within the race 8 of the plate 7 This plate 11 has a central aperture 14., through which passes the shank 5 of the hub, and in the inner face of this plate 11 is formed aplurality of recesses 15, in which are mounted the spindles 16 of the rollers 17 19 indicates annular collars which loosely encircle the shank 5, one being arranged on annular race 21, and in said race are partially mounted theballs 22. To secure said balls in position, I employ an annular plate 23, formed with a race 24:, said plate being secured by any suitable means upon the outer end of the shank 5 of the axle, and in Fig. 1 of the drawings I have illustrated this annularplate 23 as being secured upon the same by means of a pin 25. Mounted between the annular plate 20 and the central partition 3, carried within the tubular casing 1, are a plurality of rollers similar in construction to those mounted upon the opposite side of the partition. To protect the annular plates carried within the enlarged tubular end 2, I provide a cap 26, havings threads 27, which engage threads 28 of the enlarged tubular end 2.
